Antimatter is made up of "antiparticles" that have the same mass as corresponding particles of matter, but an opposite charge. For example, the antimatter counterpart of a positively charged ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from ...

Instead of K 2 mesons, the team focused on particles called beauty-lambda baryons (Λ b) and their antiparticles. If CP symmetry is at play, then Λ b and anti-Λ b particles should decay at the ...

The new measurement from LHCb has found differences between baryons and antibaryons, which are made of three quarks and three antiquarks respectively. Significantly, baryons make up most of the known ...

The only place that's likely to happen is at the very center of our galaxy. And, for a while, there was an excess of radiation coming from the galactic core that people thought might be due to dark ...

New heaviest exotic antimatter nucleus Scientists teasing through six billion particle smashups detect roughly 16 'antihyperhydrogen-4' particles Date: August 21, 2024 Source: DOE/Brookhaven ...

A newly found antiparticle contains the heaviest antimatter nucleus that has ever been detected. It could potentially hold the secrets to how our universe came to be. The antimatter nucleus is called ...

Physicists have created the heaviest clumps of antimatter particles ever seen. Known as antihyperhydrogen-4, this strange stuff could help us solve some of the most puzzling physics mysteries.

A variety of exotic particles and antiparticles emerge from these collisions. Many of them decay almost immediately, but their decay products can be detected and compared with theoretical predictions.
